The Content of Anthocyanins in Cowpea ( (L.) Walp.) Seeds and Contribution of the Gene Cluster to Their Coloration Pattern.

The intensively pigmented legumes belonging to and spp. are valued as an essential component of healthy nutrition due to their high content of flavonoids. In this context, we used the accessions of with different colors of seed coats from the N.

Autofluorescence-Based Investigation of Spatial Distribution of Phenolic Compounds in Soybeans Using Confocal Laser Microscopy and a High-Resolution Mass Spectrometric Approach.

In this research, we present a detailed comparative analysis of the bioactive substances of soybean varieties k-11538 (Russia), k-11559 (Russia), k-569 (China), k-5367 (China), k-5373 (China), k-5586 (Sweden), and Primorskaya-86 (Russia) using an LSM 800 confocal laser microscope and an amaZon ion trap SL mass spectrometer. Laser microscopy made it possible to clarify in detail the spatial arrangement of the polyphenolic content of soybeans. Our results revealed that the phenolics of soybean are spatially located mainly in the seed coat and the outer layer of the cotyledon.

Identification and Spatial Distribution of Bioactive Compounds in Seeds (L.) Walp. by Laser Microscopy and Tandem Mass Spectrometry.

The research presents a comparative metabolomic study of extracts of seed samples from the collection of the N.I. Vavilov All-Russian Institute of Plant Genetic Resources.
